MIT physicists introduce a concept for a “neutrino laser” — a burst of neutrinos that could be produced by laser-cooling a gas of radioactive atoms down to temperatures colder than interstellar space. Such a laser could be used as a new form of communication or a new source of radioisotopes in medicine.
The Europlanet Science Congress 2025 will be held jointly with the annual meeting of the American Astronomical Society’s Division of Planetary Science (EPSC-DPS2025) from 7–12 September 2025 at Finlandia Hall, Helsinki, Finland. With around 1800 participants expected to join in person and online, it will be the largest planetary science meeting held to date in Europe. Press briefings will be livestreamed and press notices on presentations of interest to the media will be issued by the EPSC-DPS2025 Press Office during the meeting.
In a recent study published in the National Science Review, researchers from China proposed an Open and Shared Sustainable Mega-Constellation (OSSMC) to address the critical issue of space sustainability. By integrating a novel "Sensors+Network+AI" (SNAI) satellite architecture and a "cloud-pool-terminal" (CPT) paradigm, the OSSMC is proposed for the development of space-based intelligence. Only 48,000 intelligent satellites can meet all kinds of service needs of global users, which provides a Chinese solution for building a community with a shared future for mankind in space systems.
